1 FY 2017 Greenhouse gas reporting manual and criteria PwC China and Hong Kong

2 Greenhouse gas reporting manual and criteria Purpose This document outlines the standards, boundaries, methodolo gy and data sources that PricewaterhouseCoopers Limited China and Hong Kong ( PwC ) uses to measure and report greenhouse gas (GHG) emissions. It is intended to form the basis for the measurement, verification and public reporting of GHG emissions. The document will be reviewed at least annually to reflect relevant developments, such as changes in the business, revised methods of measuring or capturing data, or changes in external standards. This document is also based on and aligned to the PwC Global Corporate Responsibility Reporting Manual, which includes detailed information on measuring and reporting GHG emissions, and is itself updated annually. Any such revisions will also be reflected in this China / Hong Kong specific document. Standards and principles We calculate our greenhouse gas (GHG) emissions by applying the requirements and principles of: ISO Greenhouse gases, Part 1: Specification with guidance at the organisation level for quantification and reporting of greenhouse gas emissions and removals and; Greenhouse Gas Protocol A Corporate Accounting and Reporting Standard (2004) Organisational boundaries PwC applies the operational control approach to the calculation of its greenhouse gas emissions inventory as defined by the GHG Protocol. This includes offices in Mainland China, Hong Kong and Macau, and all PwC individuals working within Mainland China, Hong Kong and Macau (includi ng those employed by other PwC member firms but based within China, Hong Kong or Macau). PwC office space which is sublet to other entities is excluded. Operations within Mainland China, Hong Kong or Macau that are owned and controlled by other PwC membe r firms, such as joint ventures and offshore operations, are excluded. Individuals who are employed locally but deployed or based any where in the PwC network outside Mainland China, Hong Kong or Macau are excluded. Companies that PwC s insolvency practice and other lines of service control operationally on a temporary basis are excluded as data collection is impractical. Scope of reporting and operational boundary PwC includes all direct (scope 1) and indirect energy (scope 2) emissions in its greenhouse gas emissions reporting. We also include certain other indirect (scope 3) emissions that result from the operation of our business. These were determined based on the criteria listed for scope 3 emissions in the GHG Protocol. A complete explanation of all scope 3 emissions generated from activities influenced by PwC and a rationale for their inclusion / exclusion from the GHG inv entory is included in Appendix B.

3 Emission factors Where available, PwC uses the latest published GHG emissions factors from local authorities, and supplements these with other internationally recognised GHG emissions factors where local factors are not available. These include : 2017 Guidelines to Defra / DECCs GHG Conversion Factors for Company Reporting 2016 Baseline Emission Factors for Regional Power Grids in China (2016 年度中国区域电网排放因子 ) Guidelines to Account for and Report GHG Emissions and Removals for Buildings (Commercial, Residential or Institutional Purposes) in Hong Kong 2010 Hong Kong Electric Sustainability Report 2016 CLP Sustainability Report 2016 CEM Sustainability Report 2016 Guidelines for Accounting and Reporting Greenhouse Gas Emissions Other Industrial Enterpris es (Trial) April 2015 Estimations and restatements In line with our principles, we look to ensure that our data is as complete as possible. However, if it isn t possible or realistic to gather all data resulting in the need for estimates, these will be m ade clear in this document within the reporting specifics for each source of emissions (in Appendix A). Every effort is made to ensure that data we report is accurate and our processes are designed to support this. However should updated data be available for prior y ears, restatement is considered if it results in a discrepancy of at least 5% of the total reported data. Where we ve done this we ll provide details in the data notes supporting the restatement/s. If a new emissions source is included, prior year annual figures will be restated, as per the Greenhouse Gas protocol. Carbon emissions may be restated even when there is no change in consumption data due to updates to published emissions factors. Baseline and reporting period PwC uses the internally verified GHG emissions data from FY 2011 as the baseline year, and the annual reporting period for GHG emissions is the 12 months ending 30 June. Calculation methodology PwC selected the calculation-based quantification methodology as there are appropriate emission factor guidelines that have been released by authoritative sources covering PwC s reported activities. Consumption data has been collected from key data sources including energy invoices, reports provided by suppliers (such as building managers, travel providers and paper suppliers) and internally generated consumption reports (such as expenses claimed). In instances where actual data was unavailable, emissions were estimated by applying best available information from other reliable external sources. A complete explanation of the calculation methodology for each data source is included at Appendix A.

4 Data Collection From FY 2015, a Data Collection Manual has been made available to all non-centralised data owners to improve data accuracy and reliability specifically by ensuring consistent methods for collecting and retaining source evidence, and consistent methods of recording and transcribing raw data to templates.

5 Appendix A - Sources of emissions and rationale Direct emissions (scope 1) PwC s direct emissions result from owned and controlled vehicles (cars, vans or buses). Energy indirect emissions (scope 2) PwC s energy indirect emissions arise from the consumption of electricity and heat within leased office space. Other indirect emissions (scope 3) ISO Part 1 Section states that an organisation may include other indirect emissions within its GHG inventory based on the requirements of the GHG programme, internal reporting needs or the intended users of the GHG inventory. The GHG Protocol (p 30) indicates that organisations should determine which other indirect emissions categories are relevant based on the following criteria: They are large (or believed to be large) relative to the company s direct and energy indirect emissions; They contribute to the company s GHG risk exposure; They are deemed critical by key stakeholders; There are potential emissions reductions that could be undertaken or influenced by the company. PwC reviewed all business activities to assess and determine whether specific scope 3 emissions should be included or excluded from the GHG inventory. Each scope 3 emission is discussed below and the rationale for inclusion or exclusion is provided. T able 1 Rationale for inclusion / exclusion of certain scope 3 em issions sources Scope 3 categories In / Out Related PwC Activities Rationale for inclusion / exclusion 1. Extraction and production of purchased materials and services a) Purchase of the following materials: 5 office equipment and technology 4 paper (including paper stationery) 5 stationery (excluding paper products) 5 food and beverages 5 other (eg. gifts, uniforms, newspapers) b) Purchase of services at external venues: 4 overnight accommodation 5 external events / training / conferences These materials do not produce emissions when used but emissions are likely to occur during their production and manufacture. Relevant and comprehensive data for many materials are not yet available and therefore are not included. Paper (including paper stationery) is the only exception. It has been included as it is a significant material used by PwC and some reliable data is available to estimate the GHG emissions from its production. The level of paper usage is also an area that can be influenced by actions taken by PwC moving forward. We will continue to review the adequacy of supporting data for other activities and consider annually whether to include additional activities within our GHG inventory. The use of overnight accommodation is a significant part of PwC s operational business travel activities. Estimations can be made on the potential GHG emissions released from these activities through publicly available data and PwC has therefore included these emissions in the GHG inventory.

6 Scope 3 categories In / Out Related PwC Activities Rationale for inclusion / exclusion Hiring of external venues for events, training or conferences is kept to a minimum, with most such activities taking place within PwC leased office and meeting spaces. GHG emissions from these activities are therefore immaterial and not included. 2. Transport related activities c) Purchase of the following services: 5 other professional services (eg. marketing) 5 telephone / internet services 5 external publishing / printing a) Transportation of purchased products: 5 office equipment and technology 5 paper (including paper stationery) 5 stationery (excluding paper stationery) 5 food and beverages Purchased services do not produce emissions when obtained but emissions are likely to occur during their preparation and distribution. Relevant and comprehensive data for GHG emissions within these services are not yet available and therefore these activities have not been included. We will continue to review the adequacy of supporting data for other activities and consider annually whether to include additional activities within our GHG inventory. Most purchased products are delivered by a variety of different suppliers with limited visibility over the location of the warehouse and delivery distances. As there is limited relevant and comprehensive data available these have been excluded from the GHG inventory. We will continue to review the adequacy of supporting data for these activities and consider annually whether to include them within our GHG inventory. 5 other (eg. gifts, uniforms, newspapers) b) Business related travel: PwC employees spend a significant amount of time 4 Air travel at client offices or in other PwC offices (both domestically and overseas) while completing project work. The transportation of employees to 4 Taxis these sites is a significant part of the firm s impact on the environment. GHG emissions generated by 4 Car rentals the combustion of fuel through business related travel is included in the GHG inventory. The 4 Car travel to clients inclusion of business travel is also expected by employees and clients, and is an emission source 5 Trains / buses to clients that can be influenced by PwC s future actions. However, comprehensive data for train/buses travel is limited and these have been excluded from the GHG inventory. We will continue to review the adequacy of supporting data for these activities and consider annually whether to include them within our GHG inventory. 5 c) Employee commuting to Employee commuting has not been included in the

7 Scope 3 categories In / Out Related PwC Activities Rationale for inclusion / exclusion and from work GHG inventory. All PwC offices are located in the central business district of major cities and are therefore very accessible for employees by public transportation. Where company transport services are provided (shuttle buses, leased cars and airport transfers) these emissions are included as part of 2 (b) above. 5 d) Transportation of products sold (eg. courier) As a professional services organisation there is very limited delivery of materials or documents made to clients, so transportation of products sold has not been included in the GHG inventory. 5 e) Transportation of waste Collection of waste occurs at varying frequencies, with limited visibility over the number of collections and distance travelled to waste management facilities. As there is limited relevant and comprehensive data available these have been excluded from the GHG inventory. We will continue to review the adequacy of supporting data for these activities and consider annually whether to include them within our GHG inventory. 3. Electricity related activities not included in scope 2 4. Leased assets, franchises and outsourced activities 4 a) Generation of electricity that is consumed through transmission and distribution systems 5 b) Electricity used by PwC leased equipment off-site a) Leased office space including: 5 Base building electricity consumption 5 Base building natural gas consumption Transmission and distribution losses incurred from the consumption of electricity from PwC s tenancy electricity (scope 2) have been included in the GHG inventory. Transmission and distribution losses incurred from the consumption of electricity in PwC s portion of base building electricity (scope 3) are excluded as reliable consumption data is currently unavailable. We will continue to review the adequacy of supporting data for these activities and consider annually whether to include them within our GHG inventory. The use of leased laptops offsite is part of PwC business activities. For the sake of completeness, electricity consumed by the leased laptops used offsite should be included in the GHG inventory. However, comprehensive data for the number of leased laptops used offsite are limited. We will continue to assess the accuracy of supporting data for the relevant areas annually whether to include them in our GHG inventory. Reliable base building energy and refrigerant data is current unavailable, so emissions released from PwC s portion of base building energy, air conditioning and refrigeration are not included in the GHG inventory.

8 Scope 3 categories In / Out Related PwC Activities Rationale for inclusion / exclusion 5 Base building diesel consumption 5 Base building refrigerants released from air conditioning and refrigeration units 5 b) Leased computers, photocopiers and printers The electricity used while operating leased computers, photocopiers and printers is included in energy indirect (scope 2) emissions. The embodied GHG emissions within the leased equipment have not been included in the GHG inventory for the same reason as the purchased products (see section 1(a)). 4 c) Leased vehicles PwC operates shuttle buses and other leased vehicles for airport transfers and inter-office movement in some locations. Emissions from these sources is included within section 2 (b) above. 5. Use of services 6. Waste disposal 5 a) There are no specific emission-generating activities in the end use of our services. 5 a) Disposal of waste generated in operations sent to landfill 5 b) Wastewater treatment General waste collected at PwC offices and taken to landfill is controlled and operated by building management service providers, and currently no reliable data is available. Billing of wastewater from PwC premises is currently included in overall service agreements with building management and/or landlords, so reliable measurement is currently not available. We will continue to assess the accuracy of supporting data for the relevant areas annually whether to include them in our GHG inventory.
